Windows FAQs, answered by experts

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

Before you replace your windows, check your home warranty. Many home warranties don’t cover windows at all, while some have specific clauses about what they will and will not cover and what might void the warranty. If you have any questions, reach out to your insurance specialist, and never make assumptions.

Impact windows can last between 10 and 40 years, depending on how much wear and tear they receive. This is roughly within the range for standard windows; standard windows tend to last between 15 and 50 years. You can extend your windows’ lifespans by performing regular maintenance on them and ensuring they are installed correctly.
